Function

Neurophysins are carrier proteins which transport hormones from the hypothalamus to the posterior pituitary gland[1].

  • Neurophysin-1 transports oxytocin.
  • Neurophysin-2 transports vasopressin.
  • Oxytocin is used to start labor and increase its speed.
  • Vasopressin functions to retain water in the body and to constrict blood vessels.

Disease

Mutations in neurophysin-2 are associated with familial diabetes[2].
